The high P/E big tech companies enjoy is on basis of the implicit expectation to keep growing fast[1], if that on confidence on growth is no longer there, then price will reflect closer to a more traditional tech stock.
Tesla trades at P/E of 185x, Amazon - 58x, Microsoft - 35x, Google - 29x and FB - 23x[2]. I think it accurately reflects the market expectation of their respective future growth.
